摘要： A stator of an electric machine comprises a frame mounted on a base by means of supporting feet. A laminated core is supported in the frame with its laminations clamped together in the axial direction by support ribs located in slots in the frame. The support ribs are equally spaced around the periphery of the core said only the support ribs adjacent the maximum rigidity portions of the frame are attached thereto and made resilient. Such an arrangement of resilient links between the core and the frame tends to minimize the stator vibrations transmitted to the frame and the base. The support ribs not attached to the frame are provided for uniform compression of the core and may be rigidly secured to the surface thereof.

摘要： A device for securing the end connectors of an electric machine stator winding, wherein the magnetic circuit stacks thereof are clamped axially by means of elements arranged on the end surfaces of the stator core, comprises two insulating conical rings, the end connectors of the winding being arranged between the conical surfaces of the rings. The outer conical ring is connected with the clamp board and is being adapted to move axially with respect to the clamp board. The inner conical ring is retained in an axial direction by means of axially arranged rods pivotally connected with the outer conical ring by means of supports. The suports are pivotally secured in the elements axially clamping the magnetic circuit stacks by means of radially arranged rods. The proposed structure provides for dependable securing of the end connectors of the winding, such that damage of insulation and loosening are avoided during the course of operation.

摘要： Disclosed is an electric-machine stator bar winding provided with an arrangement for electric insulation of end connections of extreme bars of different phase winding groups, that comprises box-type dielectric screens encompassing said connections. Each of the screens is built up of channel-shaped members made from a thermosetting material and having bent end portions. These members are so installed that adjacent walls of a pair of the screens in one interphase region of the end windings, lying in the radial planes of the stator are formed by adjoining walls of the angle-shaped members, the walls of the screens which are opposite to the adjoining walls are formed by the walls of the channel-shaped members, whereas the walls of the screens, lying in the tangential planes of the stator are formed by the flanges of the channel-shaped and angle-shaped members, the bent end portions of these members adjoining a part of involume sections of the bar end portions. The end windings have members used for tangential fastening of the bar end portions, which members are made from an electrically insulating moulding material, arranged in the interphase regions, and entering the regions of arrangement of the involute sections of the bars.
